Description

Technical Field

[0001] This utility model relates to the field of ground waterproofing technology, and in particular to a novel cement-based waterproof chassis structure. Background Technology

[0002] The design and construction of a bathroom shower room is a comprehensive project that requires consideration of multiple aspects such as aesthetics, practicality, and safety.

[0003] In existing technologies, waterproofing of bathroom shower enclosures mainly involves the following steps: applying waterproofing material to the floor, then leveling with cement mortar, and finally laying floor tiles. However, this traditional construction method has the following technical problems: the multiple steps of applying waterproofing material, leveling, and laying floor tiles make the construction process cumbersome; due to aging of the waterproofing material and construction quality issues, the waterproofing layer is easily damaged, resulting in a short waterproofing lifespan; during construction, weak adhesion between the waterproofing layer and the base layer and floor tiles can easily lead to cracks and leaks. To solve these problems, those skilled in the art have proposed an integrated bathroom chassis structure. A single chassis provides good integrity, effectively preventing water penetration, and simplifies the construction process, improves construction efficiency, and reduces maintenance difficulty. However, the integrated bathroom chassis structure still poses a risk of leakage at the drain location. Currently, to solve this problem, technicians have adopted the method of repeatedly applying waterproofing layers, but the effect is not ideal. Summary of the Invention

[0019] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. It should be understood that the described embodiments are merely some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] To further improve the waterproofing effect of cement-based waterproof chassis and simplify the construction process, such as Figure 1-3 As shown, this embodiment provides a novel cement-based waterproof chassis structure, including: a waterproof chassis 1, a pre-coated waterproof layer 2, a prefabricated floor drain component 3, a sealing component, a water flow cover 4, a bottom mortar layer 5, a top mortar layer 6, a brick surface layer 7, and a water-blocking strip 8.

[0021] The waterproof base 1 serves as the foundation of the overall structure, providing both support and waterproofing. The inner surface of the waterproof base 1 is pre-coated with a waterproof layer 2, effectively enhancing its waterproofing capability and maintaining good waterproofing even during construction or long-term use. A drain installation hole 101 is provided on the waterproof base 1, within which a prefabricated drain component 3 is installed for connecting the drain, ensuring waterproof sealing and structural stability at the drain location and reducing the risk of leakage.

[0022] A smooth transition surface 102 is provided at the junction of the bottom wall and the side wall of the waterproof chassis 1 to facilitate the application of the pre-coated waterproof layer 2.

[0023] The design of the prefabricated floor drain component 3 fully considers the tight connection with the waterproof base plate 1 and the waterproof sealing performance. The prefabricated floor drain component 3 includes: interface sleeve 31, fixing base pipe 32 and installation ring sleeve 33.

[0024] The interface sleeve 31 is located in the upper part of the drain installation hole 101. A grooved plate 311 is provided on the outer side of the top of the interface sleeve 31. After the prefabricated drain component 3 is installed, the upper surface of the grooved plate 311 is flush with the upper surface of the waterproof base plate 1 to ensure flatness and facilitate the laying of subsequent construction layers. A first recessed groove 1011 is opened at the top opening of the drain installation hole 101. After the prefabricated drain component 3 is fixed on the waterproof base plate 1, the grooved plate 311 is located in the first recessed groove 1011. The design of the first recessed groove 1011 serves two purposes: first, it limits the position of the interface sleeve 31 after installation, ensuring accurate positioning and facilitating the screwing in of the installation ring 33; second, it increases the overall structural stability and prevents displacement.

[0025] The setter tube 32 is located in the lower half of the drain mounting hole 101. A limiting plate 321 is provided on the outer side of the bottom end of the setter tube 32. A second recessed groove 1012 is opened at the bottom opening of the drain mounting hole 101, and the limiting plate 321 is set in the second recessed groove 1012. The function of the limiting plate 321 is to ensure that the prefabricated drain component 3 can be accurately positioned after installation and to fit tightly with the bottom opening of the waterproof base plate 1. The design of the second recessed groove 1012 allows the limiting plate 321 to be firmly embedded therein, thereby improving the overall stability of the prefabricated drain component 3.

[0026] The bottom of the second sinking trough 1012 and the upper surface of the limiting plate 321 are provided with matching toothed grooves 34. The toothed grooves 34 are designed to provide an additional locking mechanism to ensure a tight fit between the limiting plate 321 and the waterproof chassis 1, and to prevent the components from shifting due to vibration during construction or use.

[0027] An annular groove 312 is formed on the inner wall of the lower half of the interface sleeve 31, providing space for an internal threaded connection. An external thread is formed on the outer wall of the mounting ring 33 to mate with the internal thread in the annular groove 312 of the interface sleeve 31. Internal threads are formed on the groove wall of the annular groove 312 and the inner wall of the setter tube 32, mate with the external thread of the mounting ring 33, forming a threaded connection.

[0028] The assembly steps for prefabricated floor drain component 3 are as follows:

[0029] First, place the interface sleeve 31 in the upper part of the drain mounting hole 101 of the waterproof chassis 1, ensuring that the pressure plate 311 is embedded in the first sinking groove 1011 and keeping the interface sleeve 31 horizontal.

[0030] Then, place the locking base tube 32 in the lower half of the drain mounting hole 101, ensuring that the limiting plate 321 is embedded in the second sinking groove 1012 and cooperates with the toothed groove 34;

[0031] Then, from below the waterproof base plate 1, screw the mounting ring 33 into the drain mounting hole 101, so that its external thread connects with the internal thread in the annular groove 312 of the interface sleeve 31 and the internal thread on the inner wall of the set base tube 32. Continue to tighten the mounting ring 33 until the interface sleeve 31, the set base tube 32 and the mounting ring 33 are tightly connected by threads to form a stable whole.

[0032] Through the above structural design, the assembly process of the prefabricated floor drain component 3 is simple and quick, requiring no complicated tools or professional skills, and can ensure that the prefabricated floor drain component 3 is stable and reliable on the waterproof chassis 1, and is not easy to loosen; the design of the fixing base pipe 32 and the interface sleeve 31, combined with the sealing components, forms a good waterproof sealing effect, effectively preventing water leakage. In addition, if it is necessary to replace the floor drain or perform maintenance, the prefabricated floor drain component 3 can be quickly disassembled without affecting the waterproof chassis structure of other parts.

[0033] A mounting groove 3211 is provided on the lower surface of the limiting plate 321, and a mounting plate 331 is provided on the outer side of the bottom end of the mounting ring 33. The mounting plate 331 is set in the mounting groove 3211. This part is designed to further ensure the accuracy of the prefabricated floor drain component 3 during assembly and the stability after assembly.

[0034] A drain support 332 is provided on the inner wall of the mounting ring 33. The drain support 332 is used to support the drain and ensure that the drain can be stably positioned in the predetermined position after installation. A sealing ring groove 333 is formed on the drain support 332. The sealing assembly includes a first sealing ring 9 and a second sealing ring 10. The first sealing ring 9 is disposed in the sealing ring groove 333, and the second sealing ring 10 is disposed above the drain support 332. Specifically, after the drain is installed, the second sealing ring 10 is located between the drain and the interface sleeve 31 and the mounting ring 33.

[0035] The first sealing ring 9 forms a first line of defense between the drain base 332 and the drain, while the second sealing ring 10 forms a second line of defense. This dual-sealing design of the first sealing ring 9 and the second sealing ring 10 significantly improves the waterproof performance of the drain location, effectively preventing water leakage. The design of the drain base 332 ensures the stable position of the drain within the prefabricated drain component 3, reducing the risk of seal failure due to drain movement.

[0036] A drain cover 4 is installed above the prefabricated floor drain component 3. The drain cover 4 is made of stainless steel, which is resistant to chemical corrosion and suitable for humid environments, such as bathrooms and other floor drain installation areas. A water passage hole 401 is provided on the drain cover 4, allowing water to flow smoothly through the drain cover 4 into the floor drain, ensuring unobstructed drainage and preventing larger debris from entering the drainage system, thus providing a certain degree of filtration.

[0037] A bottom mortar layer 5 is placed between the waterproof base plate 1 and the structural floor slab 11, and a top mortar layer 6 is placed between the waterproof base plate 1 and the brick surface layer 7. A water-retaining strip 8 is fitted over the top edge of the waterproof base plate 1 through the top mortar layer 6. Through the placement of the bottom and top mortar layers 5 and the installation of the water-retaining strip 8, the new cement-based waterproof base plate structure forms a multi-layered waterproof system, greatly improving the overall waterproof performance, helping to disperse and buffer stress between different material layers, and enhancing the stability and durability of the structure.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
